Abstract
A flat roof drainage system is disclosed which utilizes a low point column head which allows the roof to be drained at the center of a structural member located at the low point of the roof. More specifically, the low point column head is a structural extension of a building column and is adapted to permit the attachment of support beams at the column head as well as the placement of a roof drain at the center of the column head so that the roof drain can be place directly at the lowest area of the roof to eliminate standing water.
Claims20
A roof drainage system for a roof having a periphery, the roof drainage system comprising:
- at least one load-bearing column head at a top of a structural column for supporting the roof, the column head being positioned below at least a portion of the periphery of the roof and having an open top end facing the roof and an open bottom adjacent the top of the structural column;
- an attachment arrangement for attaching roof support beams at the column head;
- a roof drain having a drain bowl positioned at the open top end of the load-bearing column head adjacent to the roof and a drain pipe leading out of the column head at the open bottom of the load-bearing column head adjacent to the top of the structural column;
- roof support beams attached to the load-bearing column head which each slope toward the load-bearing column head;
- and
- roof decking placed on the roof support beams and sloped to drain from all directions toward the roof drain.
A roof drainage system for a roof having a periphery, the roof drainage system comprising:
- a load-bearing at a top of each of a plurality of structural columns for supporting the roof, each column head being positioned below at least a portion of the periphery of the roof and having an open top end facing the roof and an open bottom adjacent the top of the structural column;
- an attachment arrangement for attaching roof support beams each of at the column head;
- a roof drain having a drain bowl positioned at the open top end of each load-bearing column head and a drain pipe leading out of each column head at the open bottom thereof;
- roof support beams attached to each load-bearing column head and roof decking placed on the support beams so as to create a valley on the roof;
- and
- raised and sloped, tapered insulation panels, applied to the roof decking so as to overlie the valley to direct runoff toward the drains associated to each load-bearing column head to prevent pooling and puddles.
A load-bearing column head for attachment at a top of a structural column for supporting a roof to permit placement of a roof drain substantially at a center of the column head, the column head comprising:
- a box structure having sides and an open top and bottom;
- a box support for supporting the sides of the box without enclosing the open bottom of the box structure, the support having a pedestal for attachment to the top of the structural column;
- and
- an attachment arrangement at the side for attaching roof support beams to load-bearing column head;
- wherein the roof drain having a drain bowl is positioned at the open top end of the load-bearing column head adjacent to the roof and a drain pipe leads out of the column head at the open bottom of the load-bearing column head adjacent to the top of the structural column.
